Document Summary

John von neumann created a simplified computing model. Comprised of cpu, memory, secondary storage, input/output devices. Decodes instructions and carries out corresponding arithmetic, logic, control operations. Ddr, ddr2, ddr3, ddr4 = double data rate sdram. Storage space: data is represented in bits . Measuring in base units are impractical in contemporary computing, so they"re combined w/metric prefixes to represent larger magnitudes. Coordinates flow of instructions and data between other components of cpu. Stores values, such as currently executing instruction, operands and results of operations, and memory addresses to access. Performs arithmetical, logical, and bit manipulation operations. Collection of temporary storage locations, each w/ unique physical address. Used to store instructions and data for currently running programs. List of instructions w/associated data (look at ppt slides 20-25) Up until 2005, most cpus had only one set of core components. Now, cpus contain multiple cores, each w/own set of cu, registers, and alu.
